I think before putting dynodaze down you need to get facts correct.
The "V-tec" dyno gives acutally fly wheel readings calculated from wheel hp and coast down losses, it dont guess fly wheel the power like a DD rolling road..
LOL If you can answer me the question how does a DD rolling road give actual flywheel hp readings?? As IMO a DD rr is only good for TRUE wheel HP numbers?
(well marketed the only reason I cancled my order with Mike @ DD he could not show me how the system worked out the trasmission losses)
The picture on ebay is the base line model for £12k, inerita only pc based, the one dynodaze use has the full controller with 128 input highspeed data logging. It works really well and give correct numbers and graphs by using raw data, not fancy algorithms like thr DD to work fly wheel hp out.
Its a very good rolling road setup, its unbias as dyno daze dont sell remaps or software they just do rolling road power runs and logging and rent out to tuners to fill a void in the market. It reads simalar number to my Bosch dyno +/-2hp and about bang on wheel HP as the two DD rolling roads I use, the only variation between all four dynos is the reading at the fly v both the DDs. The reason I send people to dynodaze who want to there cars tested with other tuners map is to get rid of the bias factor. If there are issues then we will take on the added logging work to find faults.
All of my rolling road days are now ran on the dyno daze rolling road so I dont get called bias... If it was crap I am 100% sure I would not put name name aginst it.
You will find a lot of maps which aint setup on a dyno feel good on the road but dont offer the smoothest graphs, a dyno at the end of the day is a tool to
aid tuning and to gain a visual picture of whats going on.
